SkillBoss API Hub - AI Cold Email Generator

Generate personalized cold email sequences from lead data. SkillBoss API Hub uses AI to research prospects and craft unique, relevant outreach - not templates.

Setup

1. Get your API key at https://app.skillboss.co/settings (Integrations → API Keys)
2. Set SKILLBOSS_API_KEY in your environment

How It Works

This skill calls the SkillBoss API Hub (POST https://api.skillboss.co/v1/pilot) with type: "chat" to generate personalized cold email sequences for each lead. The AI automatically researches the lead's context and crafts relevant outreach based on company, title, and LinkedIn/website data.

Endpoints

All requests go to the SkillBoss API Hub unified endpoint:

POST https://api.skillboss.co/v1/pilot
Authorization: Bearer {SKILLBOSS_API_KEY}
Content-Type: application/json

Single Lead — Generate Email Sequence

Generate a cold email sequence for one lead (3–5 emails per lead). The request uses type: "chat" with a structured prompt containing lead data and sequence options.

{
  "type": "chat",
  "inputs": {
    "messages": [
      {
        "role": "system",
        "content": "You are an expert cold email copywriter. Generate personalized cold email sequences based on lead data. Each email should be unique, relevant, and high-converting. Return a JSON object with a 'sequence' array."
      },
      {
        "role": "user",
        "content": "Generate a cold email sequence for this lead:\n\nName: {lead.name}\nTitle: {lead.title}\nCompany: {lead.company}\nEmail: {lead.email}\nCompany Website: {lead.company_website}\nLinkedIn: {lead.linkedin_url}\n\nOptions:\n- Number of emails: {options.email_count}\n- Signature: {options.email_signature}\n- Campaign angle: {options.campaign_angle}\n- CTAs to use: {options.approved_ctas}\n\nReturn JSON: {\"sequence\": [{\"step\": 1, \"subject\": \"...\", \"body\": \"...\"}, ...]}"
      }
    ]
  },
  "prefer": "quality"
}

Response (200):

{
  "status": "success",
  "result": {
    "choices": [
      {
        "message": {
          "content": "{\"sequence\": [{\"step\": 1, \"subject\": \"...\", \"body\": \"...\"}, {\"step\": 2, \"subject\": \"...\", \"body\": \"...\"}, {\"step\": 3, \"subject\": \"...\", \"body\": \"...\"}]}"
        }
      }
    ]
  }
}

Parsing the result:

import json
raw = response.json()["result"]["choices"][0]["message"]["content"]
sequence = json.loads(raw)["sequence"]

Batch — Generate for Multiple Leads

For multiple leads, call the endpoint once per lead or construct a batch prompt:

{
  "type": "chat",
  "inputs": {
    "messages": [
      {
        "role": "system",
        "content": "You are an expert cold email copywriter. Generate personalized cold email sequences for each lead. Return a JSON object with a 'leads' array."
      },
      {
        "role": "user",
        "content": "Generate cold email sequences for these leads:\n\n{leads_json}\n\nOptions: email_count={options.email_count}, list_name={options.list_name}\n\nReturn JSON: {\"leads\": [{\"email\": \"...\", \"sequence\": [{\"step\": 1, \"subject\": \"...\", \"body\": \"...\"}]}]}"
      }
    ]
  },
  "prefer": "quality"
}

Response parsing:

raw = response.json()["result"]["choices"][0]["message"]["content"]
result = json.loads(raw)
leads_with_sequences = result["leads"]
